In 2007, analogue transmission on longwave from Kalundborg were suspended after 80 years of service. Longwave transmissions were resumed in DRM (Digital Radio Mondiale) at reduced power on 3 October 2008 after substantial modifications to the aerial earlier that year.
Analogue transmissions continued on mediumwave with a restricted time schedule until 27 June 2011, when the mediumwave transmitter was taken out of service and replaced by a new longwave transmitter. The analogue transmissions on 243 kHz long wave will continue until at least the end of 2014. The old analogue long- and mediumwave reserve transmitter is known to have replaced the mediumwave and DRM transmitters on longwave from 16-31 October 2009, and the antenna tower for mediumwave is still standing.
For the longwave transmitter an Alexanderson aerial is used, with two grounded 118 m steel lattice radiating towers connected by top capacitance wires. The northern tower is fed from the transmitter through a top coil, with the top coil of the southern slave tower being fed via the capacitance wires. The medium wave transmitter uses an insulated guyed steel lattice mast aerial with a height of 147 metres. All mast virtually stand in the sea on the narrow Gisseløre peninsula, which allows for excellent radiation efficiency.
